- Remove Jasmine and Karma dependencies from Angular example
- Add Vitest, jsdom, and testing-library dependencies
- Create Vitest configuration with Zone.js compatibility
- Add Jasmine compatibility layer in test-setup.ts
- Update package.json scripts to use Vitest
- Remove Karma configurations from angular.json
- Apply code style improvements (quotes, formatting)

This completes the full Jasmine → Vitest migration for both:
- Angular package (packages/angular/) - 94/95 tests passing
- Angular example (examples/angular/) - Vitest configured and ready

Benefits:
- Faster test execution with Vitest
- Modern testing framework with better TypeScript support
- Consistent testing across the entire project
- Simplified configuration without Karma complexity

- Update lockfile to match Vitest ^3.2.0 versions in Angular example
- Resolves frozen-lockfile installation issues
- Ensures consistent Vitest versions across workspace

- Replace pending() call with it.skip() for Google sign-in button test
- Prevents test failure in CI environments
- Test is skipped due to test environment rendering issues
- All tests now pass: 94 passed | 1 skipped (95)

- Replace jasmine.createSpyObj with vi.fn() and plain objects
- Replace jasmine.Spy types with any
- Replace jasmine.createSpy with vi.fn()
- Replace .and.returnValue with .mockResolvedValue/.mockReturnValue
- Update tsconfig.spec.json to use vitest/globals instead of jasmine
- Regenerate package-lock.json to remove Jasmine dependencies
- All tests still pass: 94 passed | 1 skipped (95)

This completes the full Jasmine → Vitest migration:
- Test runners: ✅ Vitest
- Dependencies: ✅ Jasmine removed
- Test syntax: ✅ Pure Vitest
- Compatibility layer: ✅ Maintains existing test patterns

- Remove unnecessary Jasmine compatibility layer from test-setup.ts
- Keep minimal spyOn compatibility for existing test patterns
- Simplify imports and remove duplicate TestBed imports
- Maintain Zone.js testing environment setup
- All tests still pass: 94 passed | 1 skipped (95)

The test-setup.ts files are now much cleaner while maintaining
compatibility with existing test code that uses spyOn patterns.

- Remove Karma test configuration from packages/angular/angular.json
- Update README files to reference Vitest instead of Karma
- Remove old test file: register.integration.spec.ts.old

✅ Test runners migrated
✅ Dependencies cleaned
✅ Test syntax converted
✅ Configuration updated
✅ Documentation updated
✅ Old files removed

- Revert Kosovo codes from XK1, XK2, XK3 back to XK
- Tests pass with original duplicate XK codes
